Blockchain was born in 2009, and it is theoretically simple to understand, in a word, blockchain is a special distributed database. Separately, the database is a "warehouse" for storing data, and since it is a warehouse, it must have two basic functions: purchase (new) and shipment (deletion). In order to meet daily needs, such as finding a certain product, counting its quantity, or a certain item is placed in the wrong place, etc., "query" and "modify" functions are also required. These are the four most basic operations of the database, "adding, deleting, modifying, and checking".
Distributed means "separate" deployment of databases. The separation here has two meanings, the physical separation and the logical separation. The physical separation is easy to understand and can be simply understood as data stored on different hosts and physically independent of each other. Why is there such a demand? Because in the context of Internet globalization, multinational Internet companies are common, and local servers in the country are crucial to improve user experience.
For example, some time ago, Apple moved its iCloud service from Hong Kong to Guizhou on the cloud, and one of the benefits is faster access.
The separation of logic is a little more difficult to understand, and the editor will give a simple example. For example, Taobao, the same account may be both a buyer and a seller, and the orders generated by the buyer and the seller can be logically separated.
Due to Taobao's huge order volume, one machine could not store all orders, so a Taobao programmer had an idea to store buyer orders and seller orders on two machines. This perfect solution overcomes both technical difficulties and business needs without losing logical integrity, and the programmer received a 36-month year-end bonus (this story is purely fictional).
A distributed database may be deployed in multiple regions and its logic may be split, but at the end of the day, it is a whole that is broken down.
Therefore, a distributed database can be simply understood as deploying a database to multiple servers according to certain rules, which can be fragmented internally, but must be a whole externally.
In this way, you may understand the past and present of blockchain.
What is special about blockchain?
Blockchain, as the name suggests, is a chain of "blocks". Its structure is a long, unconnected chain. Each of the graphs can be seen as a block, and the block contains the recorded data. Since blockchain emerged along with Bitcoin, blockchain also has a not-so-strict alias - "distributed ledger technology". This is what makes it special.
Why does the blockchain project Gongxintong say that it has great potential?
The Gongxintong system is a future new economic autonomous platform built by the Gongxintong team, which develops a future-oriented and disruptive new business model by quantifying the user's own value based on the user's behavior value incentive mechanism and algorithm and expressing it through digital points GXD.
To put it simply, it is the direct connection between enterprises and users in the advertising industry, and the speed, effect, and mutual value are all withdrawn, so that the perfect presentation of block blue forms a closed loop and helps the change of blockchain in the advertising industry. In the end, users will enjoy the value of their own Internet behavior and obtain a circulation premium, while merchants will be able to obtain accurate users at a reasonable price.
The value generated in this is self-evident, with very great business opportunities and prospects.
